KNOGKDOWN BOX.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed May 10, 1909. Serial No. 495,012.

To all whom it may concern:

Be it known that I, JosEPH KELLEY, of \Veymouth, county of Norfolk,State of Mas sachusetts, have invented an Improvement in KnockdownBoxes, of which the following is a specification.

This invention relates to knocked-down boxes, particularly shaped forshipping purposes.

It has for its object to construct a light, durable and water-tight box,which is quite inexpensive to manufacture.

Figure 1 is a perspective view of a knockdown box embodying thisinvention. Fig. 2 is a longitudinal vertical section of the same, takenon the dotted line 2-2 Fig. 1. Fig. 3 is a transverse section of thesame, taken on the dotted line 33, Fig. 1. Fig. 4 is a sectional view ofthe body of the box, in knocked-down position. Fig. 5 is an end view ofthe body of the box. Fig. 6 is a sectional detail of one of the cornersof the box. Fig. 7 is a detail of one of the corners of one of theend-pieces. Figs. 8 and 9 are sectional details of means for attachingthe body of the box to the end-pieces.

The box consists essentially of two end pieces, or side-pieces which,for convenience, are herein termed end-pieces, and a body arrangedbetween them and attached to them.

a represents the frame of one of the endpieces. It is made quadrangular,and is composed of four bars, mitered at their ends, and securedtogether by any suitable means. On one side of said frame a continuouskerf a is formed, which extends entirely around it. The two end-piecesare arranged with the kerfs on their adjacent sides or faces, to receivethe body between them, the opposite ends of which are adapted to entersaid kerfs. A panel I) of fiber-board or some equivalent tough, strongmaterial, which is light and durable, and which is preferablywaterproof, is attached tothe inside of each end-frame, the edges of thepanels terminating close to the kerfs, as shown in Fig. 7, so that thecontinuous kerfs are arranged in. the end-frames around the edges of thepan els, orthe edge of the panels may extend into the kerfs, as shown inFig. 9.

The body, with the exception of its reinforcements, is preferablycomposed of a single piece 0 of fiberboard or equivalent material. Theblank of which the body is composed is provided with-transverselyarranged grooves or creases 0', four being herein shown, of a suitablewidth, permitting it to be bent at right angles or into parallel planes,without breaking, so that it may be bent into quadrangular form, seeFig. 6, or may be knocked down and laid substantially flat as shown inFig. 4. The ends of the blank composing the body are overlapped andriveted or otherwise secured together, at 0 0 and one of the overlappingend portions is cut away, at each end, see Fig. 5, so that a continuousedge of an even thickness, (being the thickness of the fiberboard) isprovided at each end of the body. When assembling the parts the ends ofthe body are merely thrust into the kerfs in the end-pieces, and, assaid kerfs are de signed particularly to receive the ends of the body,they will be made of a width corresponding to the thickness of the blankcomposing the body, so that the body will fit snugly therein.

To secure the ends of the body in the kerfs of the end-pieces I hereinarrange in said kerfs pointed fastenings d, at suitable points,

which project inwardly in an oblique direction toward the bottom of thekerf, so that the ends of the body may be easily thrust into the kerfsover said obliquely arranged pointed fastenings, and will become engagedby said fastenings which prevent its Withdrawal. Said fastenings mayconsist of staples, see Fig. 8, arranged in recesses provided for them,the pointed ends of which terminate in the kerfs, said staples beingheld in place by other staples d, or other suitable means, in lieuthereof, may be employed. Or tacks may be driven into the end-pieceswhich pass through the ends of the body, see Fig. 9.

The corner of the body having the overlapping ends is substantiallyreinforced by said overlapping ends, but the other corners are providedwith reinforcements. As here shown, corner-pieces e of fiber-board orequivalent material are employed as reinforcements, they being made ofsuitable length to extend nearly from end to end of the body, and theblanks composing said reinforcements are creased longitudinally at orabout the middle, as at e, to provide for bending them. Saidreinforcements are secured to the body by rivets e or other means,arranged along one edge, which rigidly secure said edge to the body, andby rivets e or other means, extended through slots e arranged along theother edge, although both edges may be slotted, if desired. By providingthe reinforcements with slots 6*, movement thereof with respect to thebody, as the latter is bent is obtained. WVhen shipping the partsknocked-down the endpieces may be arranged in a pile, being laid flatone upon another, and the quadrangular bodies will be flattened down bybending two opposite corners inward and the other two corners outward,as shown in Fig.4, and when thus bent the bodies may be arranged in apile, being laid flat one upon the other, the slotted reinforcementsproviding for such flattening of the bodies.

When the parts of thebox are assembled, a seal f, of any suitabledescription may be connected with the end-pieces, which connect saidend-pieces together, and thereby effect ively seal the box.

I do not desire to limit my invention to all of the features hereinshown and described.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A box comprising a pair of end-pieces,each having a continuous kerf arranged on its side adjacent the otherand extending entirely around it, a body composed of a blank adapted tobe bent into quadrangular form and having its ends overlapping andsecured together, one of the overlapping ends of the blank being cutaway at each side periiiitting the ends of the blank to abut at suchpoints and thereby providing a body with ends of an even thickness whichenter the kerfs in said end pieces, substantially as described.

2. A box comprising a pair of end-pieces, each having a continuous kerfarranged on its side adjacent the other and extending entirely aroundit, a body composed of a blank adapted to be bent into quadrangular formand having its ends overlapping and secured together, one of theoverlapping ends of the blank being cut away at each side permitting theends of the blank to abut at such points and thereby providing a bodywith ends of an even thickness which enter the kerfs in said end pieces,and means to engage the ends of the body in said kerfs and preventwithdrawal therefrom, substantially as described. J

8. A box comprising a pair of end-pieces, each having a continuous kerfarranged on its side adjacent the other and extending entirely aroundit, and pointed fastenings projecting obliquely into said kerfs, and abody having its ends adapted to enter said kerfs and to be securedtherein against withdrawal by said pointed fastenings, substantially asdescribed.

4:. A box comprising a pair of end-pieces, each having a continuous kerfarranged on its side adjacent the other and extending entirely aroundit, staples arranged with their pointed ends projecting into said kerf,and a body, having its ends adapted to enter said kerfs and to besecured therein against withdrawal by said staples, substantially asdescribed.

5. A box having a body composed of a blank having wide transversecreases formed therein to provide for bending said blank intoapproximately parallel planes whereby said body may be bent intoquadrangular form and also flattened, and reinforcing strips attached tosaid body which extend over the creased portions thereof which likewisehave wide transverse creases formed therein, permitting them to be bentwith the blank to which they are attached, substantially as described.

(3. A box comprising a pair of end-pieces, each having a continuous kerfarranged on its side adjacent the other and extending entirely aroundit, a body composed of a blank, having wide transverse creases formedtherein, and having its ends connected together and having reinforcingstrips attached to it which extend over the creased portions thereof,which likewise have wide transverse creases formed therein andwhichterminate inside the ends of said body, the ends of said body beingadapted to enter the kerfs in said end-pieces, and means for securingthe body to the end-pieces, substantially as described.

' 7. A box comprising a pair of end-pieces, each having a continuouskerf arranged on its side adjacent the other and extending entirelyaround it, a body composed of a blank, creased transversely, and havingits ends connected together, andcreased reinforcing-strips attached tosaid body at the creased portions thereof, one edge of each strip beingslotted to receive the fastening means for said strip, the ends of saidbody being adapted to enter the kerfs in said endpieces, and means forattaching the body and end-pieces together, substantially as described.

8. A box composed of a pair of end-pieces, each consisting of a framehaving a con tinuous kerf arranged on its side adjacent the other andextending entirely around it, and panels secured to said frames, theedges of which enter said kerfs, and a body arranged with its oppositeends also extended into said kerfs in said end-pieces, substantially asdescribed.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
